Title: Combustor
Inventor: KOMAI YUKIRO
IPC: F23N1/02
Filed: 1986-10-03
Abstract: PURPOSE:To reduce the ignition noise, CO generation and fluctuation of desired temperature at the time of change by providing a controller which sets the flame transfer ignition fuel supply rate and air supply rate per unit burner at the time when a switch valve is opened for flame transfer smaller than the moderate ignition fuel supply rate and air supply rate per unit burner at the time when the burners are first ignited. CONSTITUTION:A burner cluster 1 has a flame detector 3, and the other burner cluster 2 has an ignitor 4. A fuel control valve 5 is directly connected to the burner cluster 1, and a switch valve 6 is disposed between the burner cluster 2 and the fuel control valve 5. To start burning, the fuel control valve 5 and the switch valve 6 are opened by a controller 8, and all the burner clusters 1, 2 are ignited by the ignitor 4 at pre-determined moderate ignition fuel supply rate and air supply rate. When the load became small and the fuel supply rate reduced, the switch valve 6 is closed. It is opened when they again become large. At that moment, the flame transfer is conducted at a flame transfer fuel supply rate and air supply rate smaller than the moderate ignition fuel supply rate and air supply rate. The air supply rate causes a fan 7 to be controlled by the controller 8. The safety is secured by the flame detector. The combustion gas heats a heat exchanger 9.
